How long does a red top Optima battery last?
In an application like that, they could expect to see an OPTIMA battery last up to four years. However, in a more moderate climate, like San Diego, if someone might see four years out of a flooded battery, they could see up to eight out of an OPTIMA. How the batteries are used also impacts performance and lifespan.
Why is my Optima battery not working anymore?
A warm battery can expand inside and things that should touch don’t touch anymore. Similarly, terminal contacts can break or crack internally. When cold, they may touch and flow current, but when they warm up they break contact. Normal chargers won’t always work with an Optima battery.
What’s the difference between Optima and Redtop batteries?
OPTIMA’s Absorbent Glass Mat (AGM) separators hold electrolyte like a sponge to eliminate acid spilling. Each maintenance-free battery is also completely sealed, preventing corrosion and acid spills. Compare the Differences Between REDTOP® vs. YELLOWTOP® vs. BLUETOP® Batteries.
How does a deep cycle Optima battery work?
Deep cycle batteries are designed to be discharged a lot, then charged up. In this case, a winch, a stereo, or an on-board 12V fridge scoops a lot of electricity from the battery, and then it’s refilled by your charging system. Make sure you choose the right Optima battery for what you need.
What should the voltage be on an Optima battery?
The voltage on your Optima should read 9.5-10.5 volts for at least 30 seconds. When the starter motor is turning over the engine, that is the heavy load we’re using to see how the battery performs.
How does a battery start on an Optima?
Starting batteries are designed to be discharged a little, then be charged up fairly quickly by your charging system. Basically, the starter skims off some electricity from the battery for starting, and it’s rapidly refilled once you start up.
Why does an Optima battery have a low internal resistance?
The reason for this is simple – Optimas are AGM batteries and AGMs have a very low internal resistance. The low internal resistance allows them to put out a lot of electricity and be discharged more than a regular battery. (Although repeated discharging a dark-cased RedTop or BlueTop is not good for longevity).
Why does my Optima Charger not work when it’s cold?
When cold, they may touch and flow current, but when they warm up they break contact. Normal chargers won’t always work with an Optima battery. It depends a lot on how deeply it’s been discharged. The reason for this is simple – Optimas are AGM batteries and AGMs have a very low internal resistance.
What kind of Charger do I need for my Optima?
Lastly, you should have a charger that charges AGM batteries. Many people don’t know this, but a conventional battery charger won’t work with an Optima battery that’s discharged below 10.5V. You can also use a regular battery charger with a regular battery to charge an Optima.
